Abstract
The invention provides a solid polymer fuel cell whose operational stability over time has been enhanced. A reinforced solid polymer electrolyte composite membrane for a solid polymer fuel cell according to the present invention comprises two or more polymer electrolyte membranes and one or more layers of a sheet-like porous reinforcing member, wherein the polymer electrolyte membranes provide both the upper and lower surfaces of the composite membrane, and pores in the sheet-like porous reinforcing member are substantially filled with the electrolyte from the polymer electrolyte membranes, and wherein the sheet-like porous reinforcing member contains a peroxide decomposition catalyst.
